Efficacy and Safety of Firsekibart in Patients with Acute Gouty Arthritis with eGFR Less Than 60 mL/min per 1.73 m2: Post Hoc Analysis of 24-Week Data
(KIDNEY WEEK 2025)
- P3 | "Background About 70% gout patients have chronic kidney disease (CKD) stage ≥3 (estimated glomerular filtration rate (eGFR)<60ml/min/1.73m 2 ),limiting treatment options like colchicine or NSAIDs due to renal toxicity concerns.Firsekibart,previously known as Genakumab,is a novel IgG4/λ anti-IL-1β monoclonal antibody.It is not excreted via kidney,making it a significant option for acute gout arthritis(GA) with CKD.Here,we report the clinical results of Firsekibart vs compound betamethasone(CB) in a subgroup of GA patients with eGFR<60. Treatment emergent and treatment-related adverse events were 10 (47.6%) and 7 (33.3%) in Firsekibart group,versus 11 (52.4%) and 6 (28.6%) in CB group.No serious adverse events were reported in Firsekibart group.Neitiher Firsekibart nor CB showed significant damage to kidney function. Conclusion Compared with CB,Firsekibart showed a comparable effect in pain relief and offering significant better prevention of new flares in GA..."

Firsekibart as a Prophylactic Treatment for Acute Gout Flare in Participants Initiating Urate-Lowering Therapy: A Phase 2, Randomized, Open-Label, Multicenter, Active-Controlled Trial.
(PubMed, ACR Open Rheumatol)
- "Firsekibart provided superior prophylaxis against acute gout flares compared with colchicine in patients initiating ULT, with a favorable tolerability profile, supporting its potential as a treatment option for patients with gout initiating ULT."

Efficacy and Safety of Firsekibart in Acute Gouty Arthritis Patients with Limited Treatment Options: A Multicenter, Randomized, Double-Blind, Double-Dummy, Active-Controlled Phase III Trial
(ACR Convergence 2025)
- P3 | "Patients aged 18–75 years with GA, contraindicated of, intolerance of, or unresponsiveness to NSAIDs and/or colchicine, with ≥2 episodes during the last 12 months were screened for eligibility.Patients were randomized 1:1 to receive a single subcutaneous dose of Firsekibart (200 mg) or an intramuscular dose of CB 7 mg.The co-primary endpoints were change in pain intensity from baseline to 72 hours in the most affected joint measured on VAS (0–100 mm) and the time to first new episode over 12 weeks. Firsekibart is effective and well-tolerated for acute gout flares in patients with limited treatment options, demonstrating rapid pain relief and significant superiority in preventing flare compared with CB."

Efficacy and Safety of Firsekibart in Acute Gouty Arthritis Patients with eGFR < 60ml/min/1.73m2:A Post-Hoc Analysis of 24-Week Data
(ACR Convergence 2025)
- P3 | "Background/Purpose: Approximately 70% of adults with gout have CKD (Chronic Kidney Disease) ≥stage 3 (i.e estimated glomerular filtration rate (eGFR) < 60ml/min/1.73m2), significantly restricts treatment options such as colchicine or NSAIDs due to the potential renal toxicity. Compared with a potent long-acting corticosteroid (Compound betamethasone), Firsekibart showed a comparable effect in pain relief and offering significantly better prevention of new flares in GA patients with eGFR < 60ml/min/1.73m2. The safety profile in this sub population was consistent with that of the overall study population."

China approves…new drugs, including a global first-in-class medicine
(Fierce Pharma)
- "Outside of oncology, the NMPA cleared Changchun GeneScience Pharmaceutical’s firsekibart (formerly genakumab) for certain patients with acute gouty flares. To be eligible, patients must be unable to tolerate or respond to non-steroidal anti-inflammatory drugs and colchicine, and they must not be suitable to receive steroid hormones repeatedly."

Efficacy and safety of genakumab for first-line treatment of gout flare: A phase 2, multicenter, open-label, active controlled, randomized non-inferiority trial
(EULAR 2025)
- P2 | "Compared with daily oral etoricoxib, a single 200 mg subcutaneous injection of genakumab provides faster, more sustained relief of joint pain over 12 weeks, reduces recurrence risk, and is well tolerated as a first-line treatment for gout flares."

Genakumab reduces the risk of acute gout flares during initiation of urate-lowering therapy: A phase 2, randomized, open-label, multi-center, active-controlled clinical trial
(EULAR 2025)
- P2 | "ULT options included oral allopurinol 100 mg/day, febuxostat 40 mg/day, or benzbromarone 50 mg/day. Genakumab demonstrated efficacy as a prophylaxis against acute gout flares in adults with gout initiating ULT and was generally well-tolerated. A single dose of genakumab 100 mg or 200 mg reduced the average number of acute gout flares per patient and shortened flare duration over 12 weeks, with a safety profile similar to daily colchicine. Notably, in the genakumab 200 mg group, gout flares were not observed for the entire 12-week period, a finding that will be further investigated in larger sample populations."

Common TEAEs were consistent with the expected effects of IL-1 receptor antagonists. Both doses of genakumab showed promising therapeutic effects, with a lower incidence of TEAEs compared to tocilizumab."
